This article presents a study of the variation found in the oral production of verbs in L2 French by adult beginners with Swedish as L1. The study deals with the production of the two main forms of regular verbs in spoken French, a short form /parl/ and a long form /parle/, in present-tense and infinitive contexts. Learners at beginner stages use these two forms invariantly in both finite and non-finite contexts. The aim of this study is to investigate the choice of the invariant forms made by the learners. This is done by testing the influence of lexical aspect and input frequency. The investigation is made with concrete data from input sources. The results from both a free production task and an imitation test suggest that input frequency contributes more significantly than lexical aspect, although both factors overlap for most of the studied verbs.
